摘要

As an important inorganic component of vertebrate bones and teeth, hydroxyapatite (HA) has excellent biocompatibility, bioactivity, osteoconductivity and chemical stability, and can be used as a drug-release carrier and bone tissue engineering repair material. However, when it is used alone, it often presents a few disadvantages such as large brittleness, low fatigue resistance, and easy agglomeration. In this study, to improve its mechanical properties fluorinated hydroxyapatite (FHA) was synthesized by doping fluorine ion in nanocrystalline HA in solid state through microwave sintering of the mixture of HA and MgF_2 in the presence of water as an adhesive agent. The X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR) analyses were performed to explore the formation mechanism of FHA from HA under microwave irradiation.
